Another common desalination process is Reverse Osmosis. It involves a solvent passing through a semi-permeable membrane; meaning this particular membrane only allows some molecules to penetrate or pass through. The solvent will then go into a solution with higher concentration of molecules.
In February, Yorktown introduced the Electric Green Tetra, a genetically modified black tetra fish. Like its zebra fish cousin, the GM tetra is a small freshwater fish that includes genetic material from a fluorescent coral that makes it neon-bright.

Meet the Casper Fish. The Casper fish, a transparent zebra fish (Danio), was developed at the Childrenâs Hospital Boston for use in cancer research. Casper fish are the result of a cross between 2 mutant zebra fish, nacre and roy, that produce offspring with transparent skin and scales.These transparent tissues allow scientists to see how cancerous cells spread through the fishâs body as it grows and develops.arolina currently offers 2 kits in 2 versions each for the science classroom that feature adult Casper and zebra fish: the Casper Fish Observation Kits, recommended for students in grades Kâ4, and the Anatomy and Physiology of Casper Fish Kits, recommended for students in grades 5â12.
